Colored paper bits and streamers gas launcher

ABSTRACT

A colored paper bits and streamers gas launcher comprised of a tubular container, a pneumatic pressure tank, and a switch assembly. Highly compressed gas in the pneumatic pressure tank serves as the motive propellant force of the launcher, while the switch assembly is installed at the upper extent of the pneumatic pressure tank and controls the storage and release of the highly compressed gas in the pneumatic pressure tank, with both aspects constituting a dynamic control device. Furthermore, the dynamic control device is disposed in the lower end section of the tubular container and the confetti, streamers, or other similar colored effects are situated in the upper end section of the tubular container. As such, the tubular container is held manually to operate the dynamic control device at its lower end section to propel the colored paper bits and streamers out from the upper end section by means of the highly pressurized gas to thereby achieve an ideal celebration product that is convenient and safe to operation in that it does not rely on an explosive source, is toxin-free, is noiseless, and of significant practical value.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The invention herein relates to a colored paper bits and streamers gas launcher, specifically one that is equipped with a highly compressed gas control device to govern the launching operation of colored paper bits and streamers and which is safe and does not discharge any harmful substances or produce offensive noise and, as such, the present invention is an excellent celebration product.

[0003] 2. Description of the Prior Art

[0004] During major national holidays, festivals, and even on performance stages, the jubilant atmosphere is enhanced with multi-colored confetti and other color effects or the launching of colored effects and confetti high into the air such that the descent produces greater exhilaration. However, such dispersal and launching approaches have practical shortcomings. For example, in one dispersal method confetti is placed in a large container (a colored sphere) and then the sizable container is suspended high in the air and, furthermore, specialized operating personnel are utilized because for such activities heavy equipment is necessary which in combination with the required specialized personnel involves extremely high cost. Moreover, since specialized personnel conduct the operation, the audience cannot participate in or experience the drop, which is far from ideal. In terms of launching methods, many utilize gunpowder as a propellant, the explosive force of which is not only dangerous, but also generates high noise levels as well as releases toxic substances that expose users to the risk of injury. If the risk of injury is reduced by minimizing the quantity of gunpowder, then the celebration atmosphere is diminished and achieving the best effect is difficult to realize. Therefore, the cost, safety, and effectiveness of the conventional versions require improvement.

SUMMARY OF THE INVENTION

[0005] The invention herein addresses the said shortcomings and is based on numerous years of experience in the relevant fields as well as extensive research to improve and provide a colored paper bits and streamers gas launcher capable of achieving ideal confetti propulsion and, furthermore, lowered production costs and convenient operation, with the user allowed actual participation during celebrations. The primary objective of the invention herein involves the structural integration of a pneumatic pressure cylinder and a switch assembly into a dynamic control device that is optimally safe and which utilizes no explosive source whatsoever and, therefore, does not produce the associated toxic substances or noise, while also affording easy operation as well as effectively lowering production costs because the structure is simple and requires minimal materials. Furthermore, the tubular container of the present invention is held in the hands of the user, allowing the user to manually execute the colored paper bits and streamers launching operation unassisted and thereby participate in and experience the joyous atmosphere of celebrations; the invention herein enhances the actual functions of such products and is innovative and of considerable practical value.

Furthermore, the switch assembly 3 is situated at the upper extent of the pneumatic pressure tank 2 input-output opening 21 and serves as the dynamic control device installed on the pneumatic pressure tank 2 of the colored paper bits and streamers gas launcher invention herein, the switch assembly 3 has a switch base 31 that is screw fastened to the input-output opening 21 of the pneumatic pressure tank 2, while the switch base 31 is also utilized for the hinged mounting of a press piece 32; after the press piece 32 is postured against the pressure-proof sealed cap 22 in the input-output opening 21 of the pneumatic pressure tank 2 and pneumatic pressure tank 2 is sealed by the restraint of the press piece 32, a port 321 in the press piece 32 still allows for a gas refilling position on the pneumatic pressure tank 2 as well as a restraining position of the press piece 32, and also hinged onto the switch base 31 is another switch arresting piece 33 and a tensile retaining component 34 that maintains it in position; as indicated in FIG. 2, the said switch arresting piece 33 also has on it a press lock piece 331 that is directly hinged to the other end of the press piece 32 and, furthermore, the tensile retaining component 34 maintains it firmly in position, thereby stably sealing the pressure-proof sealed cap 22 in the input-output opening 21 of the pneumatic pressure tank 2; the switch arresting piece 33 has situated on it a tug piece 332 and attached onto the tug piece 332 is a pull ring 35 such that when the pneumatic pressure tank 2 and the switch assembly 3 dynamic control device is disposed at the lower end section of the tubular container 1, the said pull ring 35 is routed through an access hole 11 in the tubular container 1 and situated outside the tubular container 1, while the upper end section of the tubular container 1 is filled with confetti, streamers (not shown in the figures), or other similar colored effects and, furthermore, are isolated from the dynamic control device by a separator plate 4. During utilization, the lower end section of the tubular container 1 is held manually and the pull ring 35 at the outside of the tubular container 1 is extracted, releasing the press lock piece 331 holding down the press piece 32 such that the highly pressurized gas in the pneumatic pressure tank 2 forces open the press piece 32 of the pressure-proof sealed cap 22, thereby enabling the highly pressurized gas to propel the colored paper bits and streamers on the separator plate 4 out of the tubular container 1 and high into the air, which gradually descend to foster a jubilant atmosphere; therefore, the invention herein is not only easy to operate, but also allows the user direct participation and experience to achieve excellent practicality.

[0016] Referring to FIG. 3 and FIG. 4, another embodiment of the invention herein, the method of triggering and colored paper bits and streamers propelling during utilization is modified; the switch base 31 in the switch assembly 3 has disposed on it a hook catch 311 body, the hook catch 311 secures a press piece 32A and hinged to the other end is a switch arresting piece 33A, with the said switch arresting piece 33A similarly having a press lock piece 331 and a tug piece 332 that provide for the functionally identical restraining position of the switch arresting piece 33A as well as a tensile retaining component 34 between the tug piece 332 and the hook catch 311 that maintains them firmly in position, while the press piece 32A of course still has an port 321 for filling the pneumatic pressure tank 2; hinged to the other end of the said switch arresting piece 33A is an extending tongue piece 333 that is situated at the access hole 11 area of the tubular container 1, with a push rod 30 inserted into the access hole 11 to shove against the tongue piece 333, the levering function of which gently triggers the disengagement of the switch arresting piece 33A, allowing the gas in the pneumatic pressure tank 2 to force open the press piece 32A and propel the colored paper bits and streamers.
